Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

copy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Made to Stick Framework

A framework for crafting ideas and messages that are understood, remembered, and have lasting impact. Based on decades of research into why some ideas survive and others die.

Core Principle

The Curse of Knowledge is the single greatest barrier to effective communication. Once we know something, we can't imagine not knowing it. This makes us bad at explaining our ideas to others.

The foundation: Sticky ideas aren't born — they're made. The SUCCESs framework provides six principles that make any idea more memorable and impactful.

Scoring

Goal: 10/10. When reviewing or creating messaging (copy, presentations, campaigns, onboarding), rate 0-10 based on SUCCESs principles. A 10/10 means the message is simple, surprising, concrete, credible, emotional, and wrapped in a story; lower scores indicate forgettable communication. Always provide current score and improvements to reach 10/10.

The SUCCESs Framework

Six principles that make ideas stick:

S - Simple
U - Unexpected
C - Concrete
C - Credible
E - Emotional
S - Stories

Not a checklist — a toolkit. Not every sticky idea uses all six. But the stickiest ideas tend to use most of them.

1. Simple

Core concept: Find the core of the idea and share it compactly.

Simple ≠ dumbed down. Simple means finding the essential core and expressing it in a compact way. It means ruthless prioritization.

The Commander's Intent:

  • Military term: If everything goes wrong, what ONE thing must we accomplish?
  • For messaging: If people remember ONE thing about your product, what should it be?

The inverted pyramid:

  • Lead with the most important thing
  • Add detail in order of decreasing importance
  • Readers who stop anywhere still got the core

Techniques for simplicity:

Technique How It Works Example
Core message Strip to the essential Southwest: "THE low-fare airline"
Analogy Explain new via known "It's like Uber for dog walking"
Generative Core idea that generates behavior "Names, names, names" (local newspaper motto)
Prioritize Force-rank what matters "If you say 3 things, you say nothing"

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
